Structural adhesives - Determination of shear behaviour of structural bonds - Part 2: Thick adherends shear test (ISO 11003-2:2001, modified)

This part of EN 14869 specifies a test method for determining the shear behaviour of an adhesive in a single lap joint bonded assembly when subjected to a tensile force.
The test is performed on specimens consisting of thick, rigid adherends, with a short length of overlap, in order to obtain the most uniform distribution of shear stresses possible and to minimize other stress states which initiate failure.
This test method may be used to determine:
-shear-stress against shear-strain curve to failure of the adhesive;
-shear modulus of the adhesive;
-other adhesive properties that can be derived from the stress/strain curve such as the maximum shear stress and shear strain;
-effect of temperature, environment, test speed, etc., on these properties.

Strukturklebstoffe - Bestimmung des Scherverhaltens struktureller Klebungen - Teil 2: Scherprüfung für dicke Fügeteile (ISO 11003-2:2001, modifiziert)

Dieser Teil der ISO 11003 legt ein Prüfverfahren zur Bestimmung des Scherver- haltens eines Klebstoffe in einer einfach überlappten Klebverbindung fest, die einer Zugkraft unterworfen wird. Um eine möglichst gleichmässige Schubspan- nungsverteilung zu erhalten und unerwünschte Spannungen zu minimieren, wird diePrüfung mit Proben durchgeführt, die aus dicken, starren Fügeteilen mit kur- zer Überlappungslänge bestehen.

Adhésifs structuraux - Détermination du comportement en cisaillement - Partie 2: Essai de cisaillement par traction sur éprouvette à simple recouvrement avec supports épais (ISO 11003-2:2001, modifié)

La présente partie de l'EN 14869 spécifie une méthode d'essai pour la détermination des caractéristiques en cisaillement d'un adhésif dans un assemblage collé à recouvrement simple lorsqu'il est soumis à un effort de traction.
L'essai est effectué sur des éprouvettes constituées de supports épais et rigides, la longueur de recouvrement étant faible, afin d'obtenir une répartition des contraintes de cisaillement la plus uniforme possible et de limiter d'autres états de contraintes qui initient la rupture.
Cette méthode d'essai peut être utilisée pour déterminer :
-   les courbes de résistance en cisaillement en fonction de la déformation jusqu'à la rupture de l'adhésif ;
-   le module d'élasticité en cisaillement de l'adhésif ;
-   toutes autres caractéristiques susceptibles d'être dérivées de la courbe contrainte/déformation, telles  la contrainte de cisaillement ainsi que la résistance au cisaillement maximales ;
l'effet de la température, de l'environnement, de la vitesse d'essai, etc., sur ces caractéristiques.

The adherends shown in Figure 1 a) have a lower bending stiffness than the continuous geometry shown in Figure 1 b). Consequently, the peel stresses at the ends of the adhesive in the specimen in Figure 1 a) will be higher than those in the specimen in Figure 1 b). However, these differences in stiffness are likely to cause a trivial deviation in the comparative results. SIST EN 14869-2:2004

NOTE A suitable steel is XC18 or E24 (check these names), Grade 1 or 2. Machine the panels or bars to be used for the adherends in accordance with ISO 683-11, ISO 1052 and ISO 4995 to the dimensions given in Figures 1 a) or 1 b) depending on which specimen configuration is chosen. 7.3 Preparation of surfaces before bonding The surfaces to be bonded shall be prepared in accordance with EN 13887 or by any other method leading to cohesive failure within the adhesive layer.
